Vendor Portals Overview

A vendor management portal enables e-procurement via self-managed supplier onboarding, submission of purchase orders and requests for quote, competitive vendor bidding, online invoicing and payment.

With a supplier management portal software, you:

  • Enable fast and standardized vendor onboarding procedure.
  • Prioritize vendors based on the predefined criteria (such as product prices, vendor’s financial health or manufacturing capacity).
  • See vendors’ products and prices transparently, which allows for fact-based negotiations over purchase order costs.
  • Reduce the time and cost of resources allocated to procurement management due to process automation (vendor onboarding, purchase order creation, invoicing, and more).

As a rule, vendor onboarding software is integrated with the company’s ERP system to unfold the process of purchase order approval and submission faster, pay invoices timely and track order deliveries. The cost of vendor portal development starts at $70,000.

How to Integrate a Vendor Portal into Business Workflows

Vendor portal software is a centralized platform for businesses to exchange information with suppliers. To ensure seamless data flows, a vendor portal may be integrated with enterprise resource planning (ERP) systems, procurement software, customer relationship management (CRM) systems, supply chain management (SCM) systems, and more.

At ScienceSoft, we most often focus on integration with ERP. The reason is that ERP systems are the central hub of most businesses, managing all major business processes. Commonly, ERP systems comprise multiple modules like fleet management, inventory management, finance management, logistics control. By integrating the vendor portal with the ERP system, businesses can ensure data flows between different departments and suppliers, automate purchase order and invoice management.

On the illustration of vendor portal integrations, we give a sample combination of ERP modules fulfilling the described functions, still a real business environment may involve more modules if required by specific business workflows.

How to integrate a vendor portal into business workflows

Buyers integrate a vendor portal with ERP

  • to extend the visibility into procurement activities beyond corporate buyers to other involved teams (e.g., production planning team).
  • to have order payment information synchronized between systems, inform suppliers on payment fulfillment instantly, and not delay order shipment.
  • to store invoices for financial reporting.
  • to inform an inventory management team about planned provision of supplies.

Suppliers integrate a vendor portal with ERP

  • to upload product prices and process price quotes from buyers faster.
  • to control product stock available for order.
  • to have order shipment information updated automatically in a vendor portal.
  • to store invoices for financial reporting.
  • to plan the production based on historical sales data.

NB! Having 35 years of experience in enterprise application integration, ScienceSoft helps establish smooth vendor portal integrations with popular off-the-shelf ERP products like SAP S/4HANA Cloud, Oracle Fusion Cloud ERP, Oracle NetSuite ERP, Microsoft Dynamics 365, Infor CloudSuite, as well as with custom-made ERPs.

How to Make a Vendor Portal Truly Collaborative

We share with you tricks that we use at ScienceSoft to make user-friendly vendor portals.

As your portal will be used as supplier onboarding software, configure supplier registration requirements to check applicants against your criteria before onboarding. This way, you will avoid the inconveniences of incomplete supplier information or suppliers incapable to meet your demand peaks.

Add automated paths for buyer-supplier communication, like buttons to request a quote or inform about delayed order delivery. Buyers should have a possibility to connect to suppliers via a portal, with no need for email or phone assistance.

Set up automated email notifications to buyers whenever suppliers add comments or change the status of purchase orders. This is done not only for streamlined communication between buyers and suppliers but for uninterrupted supply chain performance – delays in procurement entail delays up the production line.

Create user tutorials for suppliers (in text and video formats) to describe all the functions and possibilities provided by a portal.

Best for

Upon request to a vendor.

Custom-built vendor portal


The idea behind using a platform to build a vendor portal is to minimize the development costs. However, when meeting your business requirements demands too much of software customization, custom development of a vendor management portal becomes a more cost-effective alternative. A custom-built portal will be unique for each business by bringing to life tailored vendor management capabilities, like an advanced vendor rating system. Functional modules can be added in an agile manner, allowing for continuous solution evolution.

MVP launch and continuous evolution.

Why a Custom Vendor Portal Is Your Best Choice

Vendor portal example: supplier dashboard

Ready-made vendor portal solutions are a rare case for mid-sized and large businesses. They have limited capabilities, and their costs scale considerably with the number of users. ScienceSoft’s clients increasingly opt for custom implementations. Custom supplier portal solutions can automate complex, non-standard vendor management processes based on your company’s specific vendor management and procurement policies, meet specific compliance and security requirements of highly regulated industries, and seamlessly integrate with legacy internal software (ERP, inventory management software, procurement software, etc.).

We Helped a Saudi Arabia-Based Company Launch a Supplier Collaboration Platform

To help the KSA-based suppliers address the complexity of choosing a reliable shipping partner, we came up with the idea to launch the platform that would directly connect shippers and carriers serving inbound and outbound international shipments in Saudi Arabia. Relying on ScienceSoft’s experience in software development and practical knowledge of the transportation and logistics sector, we commissioned them the end-to-end design and development of our shipping services marketplace.
